Nanotechnology can be used to produce high-quality infrared (IR) detectors that could be utilised in the medical, military and environmental sectors, it has emerged.

According to Nanowerk News, scientists at Michigan State University have developed a way of producing nanoantenna boosters for IR sensors that boost image quality and reduce distortion.

Researcher Ning Xi told the news source that the team has "recently achieved a high efficient and fidelity CNT [carbon nanotube] based IR detector by exploiting field localisation using nano-antennas".

He added that the use of the nanoantenna had helped to increase the electric field present in the sensing area, which in turn has improved the photocurrent response of the device.

In related news, nanotechnology researchers at Imperial College are investigating how the way in which gold particles react with light can be used to detect explosives, as well as find infections and toxins, the Engineer reports.
